Explosive Atmospheres (ATEX) / Ex-Proof Electrical Safety

In-Zone Equipment Inspection According to IEC 60079 Standards

An invisible gas leak in the air, or tiny grains of wheat dust, can escalate into a massive explosion in seconds, triggered by a tiny arc when your circuit breaker is flipped. Is your site truly 'Ex-Proof'?

A Tiny Spark Can Cost Me a Million Dollars.

In areas such as the chemical and petrochemical industries, grain silos, and even furniture paint shops, the atmosphere contains flammable fumes/dust. Standard industrial outlets (or lighting fixtures) create micro-arcs when switched on and off. If this arc heats the flammable gas (mixed with oxygen), an explosion is inevitable.


The IEC 60079 series forms the engineering backbone of the ATEX (Atmospheres Explosibles) directives. It requires 'Zero Breach' inspections of flame-proof panel housings, Ex-compliant cable glands, and shielded power infrastructure in your facility. AES Innovation's specially certified inspectors (Ex-Technicians) periodically verify the ATEX shielding of your equipment.

Zone-ATEX Inspection Disciplines (Part 14 / Part 17)

What are our Explosive Zone Testing Criteria?

  • Ex-Proof Luminaire Enclosure (Flameproof) Integrity:
    Whether gas has entered through capillary loosening in lighting glass or aluminum panel bolts (flameproof).
  • Intrinsic Safety (Ex i) Lines:
    Measuring whether the voltage going to the sensors (via Zener barriers) is clipped to an extra low level that cannot exceed the blast energy.
  • Cable Glands and Armored (SWA) Grounding:
    Mechanical strength and tightness of the sealed brass glands where the cables enter the Ex boxes, and the flow of their armor into the main PE busbar.
  • Zone (Zone 0, 1, 2) Compliance Labels:
    Whether the Ex equipment types installed due to ATEX risk in the area (IIB/IIC for gas or Zone 21/22 for dust) are compatible.

Wrong Outlet Can Burn You and Your Facility

Installing an ordinary plastic construction site electrical outlet in a Zone 1 designated chemical process area is equivalent to planting a time bomb. In the event of a potential 'Explosion Protection Document (EPD)' inspection, having your equipment inspected with international Ex 17020 approval provides you with a strong legal safeguard.

Frequently Asked Questions

ATEX Zone FAQs for Occupational Safety and Health (OSH) Professionals.

Fine organic particles suspended in the air, such as flour, wheat dust, or wood dust (Zone 21), will instantly ignite upon contact with a projector reaching temperatures of 60-70 degrees, triggering a chain reaction of terrifying dust explosions.

Absolutely! If the panel (flameproof locking cover) bolts are to be opened, the power must never be touched until the threat of an explosive atmosphere inside has passed or full ventilation is permitted.
